ThreeSpot: selectively deleting a few off topic or rude posts would be so much more effective.
Absolutely! But in order to select correctly what should or shouldn't be deleted, you need time. Because there is currently no one on WGT's staff with enough time to devote to this, the result is today's chaos in the forums.
WGT really could try and entrust some of the experienced forum users with moderation tasks, using the generic handles WGTmod, WGTmod2, WGTmod3 as suggested above. I have myself done this for years in a forum I manage: I post there under my usual name when I discuss things, but I post there as Admin in the (rare!) cases when the forum Admin needs to speak up publicly.
I have given myself all the admin privileges for my usual nickname, so I don't need to log out and back in to the forum when performing moderation tasks; that is only needed if the Admin needs to say something publicly (which is rare!).
In the same way, if (for example) Nivlac were entrusted with the moderator's position by WGT, WGT would give Nivlac the moderation privileges, so that he could silently moderate while logged into this forum as Nivlac; but if he had to speak up publicly here in the forums (which happens rarely), he'd log into the forum as (for example) WGTmod2. We the users would have no idea who WGTmod2 was – but that doesn't matter; the important thing would be for WGTmod2 to perform his/her job correctly. WGTadmins would oversee that, and forum users could complain about WGTmod, WGTmod2, WGTmod3 etc. to WGTadmin(s) if they saw moderators abusing their privileges.
